Metal complexes of thiohydroxamic acid. Part II. Crystal structure of bis(thioacetohydroxamato)nickel(II)

Abstract

The crystal structure of Ni(CH₃CSNOH)₂ has been determined by three-dimensional X-ray diffraction methods. The crystals are monoclinic, space group P2₁/c, with two molecules in a unit cell of dimensions a= 7·52, b= 5·79, c= 10·20 Å, β= 103° 15′. The crystal structure was solved by three-dimensional Fourier syntheses and refined by least-squares calculations. The final R value over the 1102 independent reflexions was 0·12. The nickel complex of thioacetohydroxamic acid forms five-membered chelate rings, in which the metal is co-ordinated to sulphur and oxygen atoms. The molecule is found to have a trans-configuration.
